Chronometer-4 / +6 s/dayCOSC criteria

Automatic SW200-1-based 11½-ligne caliber with small seconds at 6 and date at 3 (quick-set), produced by Sellita since 2011 per Grail Watch; Grail Watch notes ETA has no direct equivalent. Caliber Corner and Grail Watch: Ø25.60mm, 5.60mm high, 31 jewels, 28,800 vph, lift angle 50°, power reserve "at least 38 hours", stop-second, hand winding, ball-bearing rotor winding in both directions, Incabloc or Novodiac shock protection, Nivaflex mainspring. The power reserve is the minimum figure from those sources; Sellita's current SW200-1 documentation gives a typical 41h for the base caliber, but the SW260-1 sheet could not be checked (sellita.ch was in maintenance on 2026-10-21). Grade accuracies are Caliber Corner's summary (Sellita's SW200-1 sheet expresses Elaboré and Top as mean rates of 7 ±7 and 4 ±4 s/day), so only the COSC range is recorded as a number. The SW261-1 is the same layout with the small-seconds pivot further from the centre (7.6mm vs 6.4mm); the SW216-1 is the hand-wound version.
